Nunberg told the New York Daily News that he's contemplating seeking treatment for alcohol abuse. "I'm a little worried about me. I'll talk more about it next week."

The former aide to Donald Trump, who was fired by the real estate mogul — twice, the last time in August 2015 — appeared on Monday in a series of increasingly bizarre TV interviews. In one, Nunberg took credit for being the brains behind President Trump's winning campaign, saying, "I came up with the wall, I came up with the Muslim ban, I came up with everything to attack Jeb Bush, all that stuff."

During a phone interview, he got another call on his cell phone and actually said live on the air, "Let me take this for two seconds, OK?" His friends reportedly began to get worried that Nunberg "had been drinking prior to dialing in to MSNBC and CNN," The Daily Beast reported.

In an evening appearance on CNN's "Out Front," host Erin Burnett said, "You're sitting very close to me, we talked earlier about what people in the White House were saying about you. ... Talking to you, I have smelled alcohol on your breath."

The mainstream media and cable news networks ate Nunberg up with a spoon. He was a loose cannon and full of charges he couldn't back up — nor did it appear that he had any first-hand knowledge about his allegations. On one show, he made big news, vowing to ignore a subpoena from Special Counsel Robert Mueller, who is investigating Russia’s meddling in the 2016 presidential election.

But Nunberg went further, telling CNN, "Trump may have very well done something during the election with the Russians."

In the Daily News interview, Nunberg backpedaled on those claims Tuesday. "I got carried away," he said. "I'm trying to just get this over with."

Nunberg declined to confirm whether he was drunk during the TV interviews, but said that he came to his senses afterward and now intends to cooperate with Mueller's investigators. "I made my point, I got my venting out," he said. "Let me just give them what they want because there's nothing there anyway."

And Nunberg seems an injured man, still struggling to make sense of his firing from the Trump campaign. "I was very close to Donald Trump," he said. "I was heavily invested in that campaign. I wasn't very good after getting fired."

Nunberg said he has agreed to appear before Mueller's grand jury on Friday and vowed to "tell the truth."

Despite the scathing headlines, Nunberg concluded that his chaotic TV interviews weren't all in vain.

"The media is stipulating, 'Oh, how could you do this? Why would you do this?' To me it's pretty cool to be the first," Nunberg said. "If you work in Gonzo-style politics, this is what you do."

Nunberg added that he also decided to go on live TV because he wanted people to know how grueling it has been to be in contact with the special counsel's office.

"I just wanted people to know my story," he said. "Why do I have to get dragged through something like this?"
